I am testing a contract which is using ecrecover function of solidity. While its testing when i go with a failed test case while debugging, it doesn't go step by step and at the end return the same error as below. What is the reason of all this?
TypeError: Cannot read property 'start' of undefined at Debugger.step (/home/aniket/.nvm/versions/node/v8.9.3/lib/node_modules/truffle/build/cli.bundled.js:322984:59) at Object.interpreter (/home/aniket/.nvm/versions/node/v8.9.3/lib/node_modules/truffle/build/cli.bundled.js:318096:22) at ReplManager.interpret (/home/aniket/.nvm/versions/node/v8.9.3/lib/node_modules/truffle/build/cli.bundled.js:203345:18) at bound (domain.js:301:14) at REPLServer.runBound [as eval] (domain.js:314:12) at REPLServer.onLine (repl.js:442:10) at emitOne (events.js:116:13) at REPLServer.emit (events.js:211:7) at REPLServer.Interface._onLine (readline.js:282:10) at REPLServer.Interface._line (readline.js:631:8)
